Why doesn't the hotel's central air conditioner work in winter?

Usually, the reason why the central air conditioner doesn't cool may be the lack of refrigerant. If there is a shortage of refrigerant, it is enough to replenish it.

If there is enough refrigerant, then check the power supply voltage and whether there is a large heat source indoors. Whether the doors and windows are open or not affects the cooling effect. The piping is too long. See if the copper pipe is too long. If the piping is too long, the heat transfer of the central air conditioner will slow down and the refrigeration effect will be weakened.

Equipment aging. After the central air conditioner is installed and used for a period of time, it needs to be maintained, cleaned and maintained. If it is not maintained for a long time, it is easy to break down and the service life of the central air conditioner will be shortened.

Different from other household appliances, the central air conditioner needs to be designed, installed and debugged before it can run normally, and the installation quality directly affects the service life and later use experience of the air conditioner. Immature installation team is easy to cut corners, or it may be because of empty installation and unreasonable configuration that the drainage pipeline leaks and the cooling and heating effect is poor.

When the outdoor temperature exceeds the set value, it is difficult for most air conditioners to transfer the indoor cold (heat) to the outdoor, and the cooling (heating) effect of air conditioners will naturally become worse. In order to avoid this situation, try to install the outdoor unit of the central air conditioner in a well-ventilated place at the beginning of installation.
